...and I've not been required to sign in with a MS account login when doing these types of update/upgrades. On the other hand, I've seen a few computers which were originally setup with a MS account login but a local login was created afterward and used for normal operations. As such, there are two logins available for the computer. My daughter's computer is like that and I don't see any reason why you shouldn't be able to change login users to the one that has a local login. I believe it should only happen one time at the end of the installation at the point where you need to log in to the computer for your normal use. As such, all available users should be listed in the lower left corner of the login screen. Choose the one you want. But the best option is to be sure and login with your normal, local login BEFORE you start the update/upgrade process. It then should be the default login after the restart.
Hope this helps.
Long story short, I had already 'updated' to "May" via DVD, but I was having issues. So I reverted back to "October" update, via my backup disc. Everything was going smoothly, so Friday, June 7th, I went ahead and downloaded and installed "May" update via "Windows Update". No issues until I got to the 'sign-in' page. FYI: PC is working fine now.
In the past I have never used a "Microsoft account" to sign in, but I didn't see any option to bypass sign-in. I did, however, have a "Microsoft account" that I had made "way back when". Logged in and all went well.
Next week I plan to go to my sister's home and update her desktop pc. I have already found out how to create an account for her, but is this "necessary"? Is there another way. Will I/we be stuck with this Microsoft "log in" ?
Thanks in advance
